In einer Meta-Analyse wurden 8 Studien mit fast 3000 Patienten untersucht. Dabei zeigte sich, dass das TE-Risiko bei Patienten mit chicken wing LAA am niedrigsten war.
“Eight studies with 2596 patients were included. Eighty-four percent (n=1872) of patients had a CHADS2 score of <2. TE risk was lower in chicken wing morphology than in non-chicken wing morphology (OR 0.46; 95% CI 0.36-0.58). Likewise, chicken wing morphology had lower TE risk than did other morphologies (chicken wing vs cauliflower: OR 0.38; 95% CI 0.26-0.56; chicken wing vs windsock: OR 0.48; 95% CI 0.31-0.73; chicken wing vs cactus: OR 0.49; 95% CI 0.36-0.66).”
